Abstract(in English) In this paper, we propose a method to extract cooperative relationships from the similarity and synchronization of posting to social media by users who have the same attribute. First, we find important words, which have temporal locality, from posting to social media by users who have the same attribute using the Kleinberg's burst detection algorithm. Next, we extract word networks, whose are used synchronously, and post timing matrices, which means the time series variation of author's cooperative relationships by the similarity between burst timing vectors. In fact, we analyze word networks and post timing matrices extracted from blog articles of a certain idol group for about 5 years. In the results, we show that the different types of cooperative relationships by the proposed method.
